connected to a lamp socket or other recep tacle, and is also adapted tosuspend a lamp shade without the use of the usual radial screws. I

Another object is to produce a fixture of this character which presentsa neat and more or less ornamental appearance.

The invention will be described in connection with the accompanyingdrawings, in which Figure 1 is a side view of an electrical receptacleadapted to be connected to a wall or ceiling, the parts constituting theshade holder being shown in cross section.

Figure 2 shows the four individual parts of the shade holder separatedand partly in section.

Figure 3 is a side view, partly in section, of a modified form of myinvention.

Referring to the drawings 10 indicates a amp base or receptacle ofordinary construc tion and consisting of porcelain or other in sulatingmaterial. The particular base illustrated is adapted to be attached to aceiling of a room, but it will be understood that the present inventionis adapted to be used in connection with numerous other forms ofreceptacles or lamp sockets. As illustrated in the drawing, thereceptacle 10 is formed with a neck 11 at the lower end of which is arib or shoulder 12 surrounding the screw shell 13 of the lamp socket.

A split ring A is adapted to be sprung over the shoulder 12 onto theneck of the receptacle. This ring is provided with a shoulder 141, and athreaded'portion 15 below the shoulder. The ring is of brass, or otherelastic material, and is split as at 16. When in position the shoulder14 of the ring rests on the shoulder 12 of the receptacle.

against the lower end of the neck of the receptacle, thus securing theparts together without any play or lost motion. lVhen thus assembled ashade may be held in the Imemher B by three or more screws 19, as shownin Figure 3.

is'in use.

Before screwing the part B onto the part A I preferably insert in thepart B a threaded ring C provided with a flange 20 adapted to be clampedbetween the flange 18 and the lower end of the neck of the re ceptacleWhen the parts A and B are screwed together tightly.

On the outside of the threaded ring C is screwed a similar, but slightlylarger, threaded ring D having a flange 21 at its lower end extendingoutward sufiiciently to support a shade, such as shown at 22 in dottedlines, without the aid of the screws 19. As stated, the screws 19 arepreferably omitted, but the skirt 23 of the member B is retained and isadapted to hide the several threaded members and produce an ornamentalfinish between the lamp base and the shade It will be notedthat thisimproved shade lamp receptacle which is provided with an annularshoulder orgequivalent supporting means at its lower or outer end. Theparts are all of comparatively light material and inexpensive but,nevertheless, suspend the shade in a substantial maunerand withoutdanger of breakage. The skirt or canopy 23 preferably extends downto thenormal position ofthe shade to give the fixture a proper finish when theparts are assembled. The ring D may be provided with small depend inglugs 24; to facilitateturning it into place, the lugs being punched outof the metalof the flange 21.

Having described the invention I What I claim and desire to secure byLetters Patent is: p

1. The combination with a lamp receptacle having an external annularshoulder,f a screw ring having an internal annular shoulder, a secondscrew threaded member adapted to draw said shoulders together, saidsecond member having an inturned annular fiange adapted tov engage theend of the receptacle, and means associated with said second member forsupporting a shade.

2. The combination'with a receptacle having a neck and an annularshoulder, of a. threaded split ring provided with an internal shoulderadapted to engage the shoulder on the receptacle, a second threaded ringcooperating with the first named ring and hav ing an internal flange,and a shade support ing ring having a flange adapted to be clampedagainst the outer end 01 the receptacle by said second member.

3. The combination with a. receptacle having an annular rib surroundingitslamp receiving portion, two cooperating threaded members eachprovlded w th a flange or shoulder to engage the inner and outersurfaces of the rib, and a shade supporting member having a flangeadapted to" be clamped agamst the outer surface of the rib.

4. The combination with a lamp receptacle. having an annular ribsurrounding its lamp receiving portion, of a split ring having athreaded portion surrounding said rib and a shoulder to engage the rib,a member having a threaded portion to engage the split ring and a flangeadapted to engage the outer part of the rib, a threaded ring having aflange adapted to be clamped between the flange of said member and therib, and a second threaded ring adapted to be screwed onto said firstthreaded ring and having a shade supporting projection at its lowermargin. V

5. The combination with a lamp receptacle having an annular ribsurrounding its lamp receivin portion, of a split ring having a threadedportion surrounding said rib and a shoulder to engage the rib, a memberhaving a threaded portion to engage the split ring and a flange adaptedto engage the outer part of the rib, a threaded ring having a flangeadapted to be clamped between the flange of said member and the rib, and

a second threaded ring adapted to be screwed I onto said first threadedring and having a shade supporting projection at its lower margin, saidmember engaging said split ring having a skirt or canopy surrounding andobscuring the several threaded members.
